Foresight: e2fsprogs Print E-mail
User Rating:      How can I rate this item?
Posted by Bill Keys   
Previous versions of the e2fsprogs package are vulnerable to multiple integer overflows which may be exploited via specially-crafted filesystems. The workaround for is to not run fsck on a filesystem to which an untrusted user has the ability to directly modify filesystem metadata. This is most commonly an issue when using a virtualization solution in which the root user for the guest OS is not trusted, and can convince the host's root user to run fsck on the guests's filesystem. Foresight Linux neither enables nor supports any form of virtualization in the default install.
